Several significant diseases, insects, and mites attack pecan trees in backyard orchards. These pests can diminish the trees’ appearance and reduce nut production.
For example, webworm webs and caterpillar feeding on the leaves can create an aesthetic concern in trees grown primarily for shade. These pests usually do not threaten the health of established trees. However, owners interested in protecting the nuts from damage must identify the pest problem and take the appropriate action.
Although planting a pest-resistant variety, removing old pecan shucks, and adopting other cultural practices can minimize some pest damage, backyard growers may also consider pesticides when cultural controls are inadequate.
